acitizenofl the v United States,r Aresidii'ig at i Fayetteville in thecounty of .Franklinand` StateofePeirnsylvania, have invented newand.useful Improvements, in` Latli and Boltspeciication.-I I

-This vinvention *i I A s aiv'mills,` the objecten vieiv` being toproing'Saivy Milla; of lwhichthe foll'oiving 'y is a duce AanA eiiic-ientmachine ,`ofVv the classiy re-` i ferred to which Iwill rapidlysaiv'fliiinber into sti-ipsnand, then.into,latliswpalingsrroofinglathsand the lileytlielma'chine em{ bodying novel, iWork feedinglmechanisi'n Which ivill .relieve the operator 'or lattendant ofthetedious and laborious v ork o'f forcing the. .W0rlothrougl1'- the'machiney by` hand" pressureI and ivhich :Will also" prevent linjury,toh'thez operator oau'secbby Ithe Work; being driven backivardly bythesaivor saws. y .v Afurther, objectyof Ithelin'vention is to providemeans'ivhereb'y the feeding mecha-- nismmay be instantly adjiistedtosuit Work of different lor 'vaiying'thiclmesses and having unevenlsurfaces, the ,fee'dingimechanisin thereafter being 'self-adjiisting inaccordance With the thickness .of the material passing' through themainline.`

A further object of ytheinvention' istO provide ymeans whereby one 'ofthe feedv` rolls may be adjusted toy an "angular position for' thevpi'irpose ofl crowding fthe 'Work' relatively short shafts 22 and22parallel against' the gageon the saiv table. 'y

With the above and'other objects in view, the invention 'consists in`vthe novel 'construction, combination and arrangement of parts, ashereindescribed, illustrated and claimed.

In the accompanying 'drawings z-Figure 1 is. a plan vie-W of a sawingmachine embodying the present invention. Fig. 2 is also a plan view withthe table and the' mechanism above the table removed. FigfA is\ an endelevation of the' machine. Fig. 4 is'a vertical longitudinal sectionthrough the machine 'takeirabout 'in 'line' 'with the sawmanl drel whichis shown in elevation. Fig. 5' is a fragmentary horizontal sectionshowing the means for adjusting the angle of one of the feeding rolls.

Referring to the drawings A designates a frame of suitable constructionto support the parts and bearings therefor hereinafter particularlydescribed.

i connected abridge oi" yhousing 2 forl the y drivingbelt 3 and drivingpulley 4' ontlie edge ofthe tablel section may be 'raised' and loweredto'give access to the mechanism `contained beneath. i The saw mandrel 5is'supp'orted in'bearings on` any desired number 0f crossbars 7 'and is,slioivnas having mounted fast on one en'd lthereof a vsinglecircularsaw -8 and on the other end thereof a plurality ofcircular'i'saws 9,.three ofsuchbeing shown in proper spaced relationyto'each othei'to' cut the lumber intolaths or the like.` "The mandrelwhich is driven primarily by the'belt 3 is connected 'by abeltI 85 to abelt Wheel 9the shaft 10 of which has fast thereon a pinion 11 whichdrives a spur gear 12. Fast on`tlie shaft 13 of the gea-r F12 arepinions 14 and`14"y f rom'ivhichrhains 15- and 15- extend aroundsprocketv Wheels 16y and :16' on shafts 17 and 17 arranged parallel tothe shaft '5 `and journaled in suitable bearings f onthe frame, theshaftsv 17 and17 having lower -feed rolls "18 and 1,8 fast thereonWith'their upper portions Working slightly.v

above the level of the top of the Work/table 1. From other sprocketWheels l19 and 19 fast on the shafts 17 and 17 sprocket chains 20 and 20extend rearwardlyV around sprocket Wheels 21 and 21 on a pairV of tojthe shafts 17 and 17 and journaled in spur gears 24 and .24"011 theshaft 25 and 25` of which mare mounted sprocket Wheels'from which chains26 and 26 extend toward the front of the "`inachine and pass aroundsprocket Wheels fast onl shafts 27 and .27 carryingiipper feed rolls-28and 28..

Each upper feed roll 28 is carried by the `free end bf anarm 29y the'rear end of 'which ispivotally mounted in relation to the table 1,being journaled on the shaft 25 lor 25 Which are shown as supported inbearing brackets 30 and 30 secured to the table and extending above thesame. Each arm 29 embodies a pair of parallel side bars as shown inFigs. 1, 4 and 5, the forward ends of said side bars being connected bya bridge piece 31. Located beneath the bridge piece 31 and passingthrough a hole in the now be seenthat by depressing the forwardextremity of the footy lever 33, the rod 32 will be thrust lupwardly andby bearing againsty the bridge3l, will lift the arm 29 and therefore therespective upper feed roll 28 carried by said arm. y

Referring, nowy to Fig. 5 it will be Vobserved that each upper feed roll528 is mounted upon a spindle 38 which is journaled in bearing members39 slotted as u 4,shown at 40 and connected by clamping bolts41to theside bars ofthe arm 29. The bearing openings in the bearing members 39are flared in ,opposite directions as indicated at '42jl and the bearingmembers are independently-adjustable by means of the bolts. or ,clampingmembers 41. This enablesthe.

spindle 39to be set at anV angle to the path of movement of the work soas to crowd the same against one of a pair. of gages or gage ystrips 43each of ,which is provided with laterally extending arms 44 slotted andadjustable by, means of clamping bolts 45 or the equivalent thereof.Brackets 46 are secured te the table land extendupwardly therefrom,serving as supports for dust shields or guards 47 which serve to preventdust from liying in the face of the operator.

In operation, the work isentered between the upper and lower feed rollsand if necessary 4the upper feed roll is elevated by means of the footlever 33 to -admit -the vvork. l 'Thereafter' the upper feed roll 28rests byv gravity on the top surface ofthe work, the feed roll being o-fsufficient 4weight to produce the necessary driving'engagemenathe feedroll rising and falling in accordance wlth any lnequallties 1n thesurface of the Work and 4being therefore self-adjusting. A

Shouldv the Work become jammed against the sawand gage, the drlvingeffect of the workl plroperly inilace on the table'. A fee feedrollsj'ma'y be instantly arrestedby dei' pressing the foot lever 33. By'slightly eantf Ying the spindle 38, the ,upper feed roll 28 will acttocrowd the Work snugly against.

the adjacent cage 43. v y

reatly increase thejout-.f, or the reason that the."v work is fedautomatically to the saws after` The machine will put of a saw millsimply being inserted'between the feed .-rolls..

"Furthermore, the feed rolls act to preirent the material fromrebounding from `the saw and injuringthe operator.- On account of theweight'of the upper feed roll, no springs are required for holding thesame 'against the work and furthermore the pressure of the upper feedroll is never excessive. When an extra heavy. piece of lumber is to vbebolted, the upper feed rolls are raised by depressing the vfoot leverandthereafter the upper feed roll will continue toholdL the Eac `upperroll maybe adjusted' and- Will operate independentlyof-'the other,'enabling the lumber to be savvevc'linto bolts 'at one side of themachine and the'bolts to be sawed into laths and'` palings onthe otherside of the machine. 5

Having thus described my invention, I claim: l v y The combination witha saw, saw-table, andside gage, of a lower feed roll on said shaft, anupper feed roll carryi'ng'arm hav ing a pivotal mounting on the uppervside ofsaid table, an'upper feedv roll carried by the free end of saidarm, a spindle on which said upper feed roll is fast, bearing memberslfor said spindleplocated 'at opposite and having flared bearing.openings, and* .sides of said upperfeed roll onsaid armv means foradjusting said bearing members independently' ofeach other to give .anan.

4gular disposition to said spindle.

In testimony whereof I aliix my signature in presence of two witnesses.
